Shoe upper



FIG. 1 is a perspective view of a shoe upper, showing my new design;

FIG. 2 is a top plan view thereof;

FIG. 3 is a left-side elevational view thereof;

FIG. 4 is a right-side elevational view thereof;

FIG. 5 is a front elevational view thereof; and,

FIG. 6 is a rear elevational view thereof.

The broken lines showing a shoe sole in the figures depict environmental matter and form no part of the claimed design. A right shoe is illustrated, it being understood that a left shoe is a mirror image thereof. The bottom plan view is not part of the claimed design. 

I claim the ornamental design for a shoe upper, as shown and described.
